BornHack Meetup at 35c3 2018-12-26

A bunch of BornHack organisers are present at 35c3.

We don't have a BornHack assembly, but we are organising a meetup on Friday the 28th at 22:00 CET. The location is the Discodrama near the rocket.

We know that many BornHack participants are present at Congress, and we look forward to seeing everyone again :)

If you've never been to BornHack the meetup is an excellent opportunity to ask questions and have a drink with us.

We have a free BornHack 2018 Badge for the first 20 people who shows up. We might also have some Gammel Dansk and Snaps.

See you there! :)

Update on the Secret Token Game 2018-08-19

Some say a token for the Secret Token Game can be found somewhere inside this image

We've also hidden two tokens somewhere on the website.

The DECT Network at BornHack 2018-08-18

We are happy to announce that this years BornHack features an experimental DECT network, courtesy of Klondike. If you have a DECT phone you can pick a 4 digit extension and asking klondike in the big blue tent near the speaker's tent to register it for you.

Phone numbers of interest include:

Numbers starting with 1 and 0 are reserved.

A big thank you to klondike for working on the DECT network. We absolutely love to see participants creating new things at BornHack. If you have something you would like to build or create to make BornHack better don't hesitate to contact an organiser!

The BornHack Secret Token Game is Live! 2018-08-18

The BornHack 2018 Secret Token Game has begun!

We have hidden a number of tokens at BornHack. They may be on the website or on physical items. They may be in the clear or they can be obfuscated or encoded.

The tokens are 31 or 32 bytes long and conform to this regular expression

If you think you found a token you have to visit the BornHack website under /token/ to see if it is valid. For example, if you found the string o7cqfeB4Zr2Kyvup087JcgVsFZrWK3Nz you would visit while logged in to register your find. If the token is wrong you will receive a 404 page.

You can go to to see a list of the tokens you've already found.

Please don't bruteforce the tokens, it would take forever, and creates an unhealthy load on our servers.

Anyone who finds all the tokens will win a price. At the Goodbye World talk wednesday we will announce the winners.

Happy hunting!

Share your ride to or from BornHack 2018-08-10

Ferry Tickets Close to Sold Out 2018-07-30

BornHack takes place on an island, and this years BornHack coincides with a music festival called Wonderfestiwall and a few other minor events which take place on the same dates.

This means that the ferries are very popular around the dates when we expect people to travel to and from Bornholm for BornHack 2018.

The ferry tickets are not sold out yet, but they will be soon. If you are traveling with a car by ferry from either Køge or Ystad and you still haven't bought your ferry ticket, now is the time.

Sponsors Needed 2018-07-20

We are still looking for sponsors for BornHack 2018. Our call for sponsors can be found on the sponsors page along with the existing sponsors. If you know of an organisation which might be interested please point them to that page.

Firefighting Equipment Added to the Shop 2018-07-12

Tents larger than 50m2 and tents with elevated fire risk like soldering irons or cooking equipment are required by fire regulations to have firefighing equipment. Specifically:

You can bring your own set or rent one from the shop.

Fridges Added to the Shop 2018-07-10

To help participants keep groceries chilled until they are needed we have fridges available. You can rent a shelf for 200,- DKK for the entire week, or a smaller drawer for 100,- DKK for the week. The prices are higher than last year because we unfortunately have no fridge sponsor this year.

The fridges look like this and can be ordered in the shop.

Renting all the space in a fridge (6 shelves + 1 drawer) enables you to move the fridge to your camp instead of keeping it in the food area. Remember the fridges are rented so we have to cover any damages.

Note: Does not come with bowls of toast bread or glasses of juice like in the picture.

You are also welcome to bring your own fridges or coolers!

BornHack First Aid Course 2018-06-20

During BornHack we want to have as many trained First Aid givers present as possible. To that end we are happy to announce a free First Aid course for up to 16 BornHack volunteers and participants.

The course takes place on the 14th of July. We begin at noon (12:00 CEST) so please arrive a bit before that time. The course takes 6-8 hours including breaks, four hours for the basic First Aid course, and some additional time for learning about treatment of festival related injuries (like intoxication).

The address is:

inQvation ApS, Erik Husfeldts Vej 7, 2630 Taastrup, Denmark

After completing the course all participants will receive an official Danish First Aid certificate, paid for by BornHack.

Drinks and light snacks will be served during the day, but we expect people to have eaten lunch when they arrive. Expect some activites on the floor, so dress accordingly.

To participate please signup on this Doodle. Maximum 16 participants.

BornHack 2018 Design Contest 2018-03-04

The creative elements of BornHack 2016 and 2017 such as taglines, color profiles, logos, and merchandise design came from the organiser group. For BornHack 2018 we would like to host a Design Contest for the BornHack community.

We are looking for participant submissions for the following design categories:

You can see older designs and assets

The designs should work in a monotone color setting where only two colors are available. We have picked green #008026 (CMYK: 1.00, 0.00, 0.70, 0.50) as the color of choice for BornHack 2018. This color will be used for various components on the website as well as the festival wristbands, and could be used in design submissions.

Submission Information

The submissions must be licensed under a Creative Commons license and cannot be a non-commercial license, as the merchandise shop should be able to sell products with the designs on. We might reach out to ask permission to remix your submission in ways that we find appealing.

The submissions should be send to with the subject "Design Contest 2018" no later than the 20th of April, 2018. The winners will be announced no later than the 1st of May.

The BornHack 2017 Badge 2017-08-14

All participants at BornHack 2017 will receive an electronic name badge. Our Badge Team has been working hard on the badge for this years BornHack. To help everyone prepare for software and hardware hacking of the badge we are releasing a few details.

The hardware is based on a 32 bit ARM Cortex M0+ from SiLabs, specifically the Happy Gecko with built in USB, and a 128x64 pixel OLED display, in addition to a bunch of extra GPIOs for expansions.

To build software for the badge you can use the arm-none-eabi-gcc toolchain, on pretty much all operating systems - see the badge2017 repository on github for more details.

Stay tuned for more updates, board layout and example code.

Unable to afford a ticket? 2017-08-02

If you want to go to BornHack, but you are unable to go because you can't afford a ticket, please contact us. We will work something out.

BornHack 2017 will take place from the 22nd to the 29th of August 2017 on the island of Bornholm in Denmark. This will be the second time BornHack takes place and it is time to make tradition.

We are looking for talented, humorous, inspiring, and/or provocative speakers to host talks, lightning talks, and workshops at BornHack.

BornHack is trying to be an inclusive event so please make sure you have read and understood our Code of Conduct.

Regular Talk

Regular talks are 45 minutes of presentation, 10 minutes of questions from the audience followed by 5 minutes of preparation for setting up the next speaker.

Please bring your own laptop with your presentation on; it should have an ordinary HDMI output and we will provide the cable to the projector. We do not guarantee that audio will work, even if your laptop supports it - please reach out to us early if this is a requirement.

We will provide you with a one-day entrance ticket free of charge, but due to our limited funds, you'll have to pay for transportation to and from the event yourself. We also encourage you to participate for the entire week, but then you need to buy a full event ticket.

Lightning Talk

Lightning talks are 10 minutes of presentation. A provided laptop will be connected to the projector at the location of the presentations. Please make sure you have your slides submitted to the content team no later than 24 hours before the lightning talk session begins.

A lightning talk is an excellent opportunity for inexperienced speakers to share an interesting idea, presentation, or maybe just a small story.

You MUST buy yourself an entrance ticket to host a lightning talk; we are unable to offer free tickets for everyone giving a lightning talk.


We have two workshop areas that will be able to host workshops for approximately 20 people per room. Workshops can be up to 3 hours per slot and can be extended for daily workshops.

If you are camping with a village, or there is a village related to your workshop, you are of course also welcome to host sessions there.

You MUST buy yourself an entrance ticket to host a workshop; we are unable to offer free tickets for everyone hosting a workshop.

  3. Propose a new speaker.
  4. Propose a new event.

We will review incoming proposals and notify you as early as possible on whether the proposal was accepted. Proposals submitted before 1st of July will be notified by us no later than the 16th of July. Late submissions are welcome, but we might be running low on available slots at that time.

Team Signups Open 2017-04-08

If you want to help make the next BornHack great then you should consider joining a volunteer team to help out.

We need help with more or less everything at this point. If you just want to help with practical jobs (carrying stuff around and things like that), then great.

If you have a drivers license, or a first aid/truck/whatever certificate, or if you're a qualified electrician, carpenter or plumber, we would love to hear about that too :)

Each team has one or two responsible people to take care of coordination and reporting to the organisers. They are the people to contact with any questions you may have before joining a team.

At BornHack 2017 all organisers and volunteers buy full tickets like everyone else. In the future our budget may allow for discounts or free tickets for volunteers, but not this year.

Finally: If you've never volunteered at an event like this before you should really consider it. It is a great way of meeting new people, and it feels good to be a part of creating a great event like BornHack.

What are you waiting for? Go join a team!

New Website Online 2017-02-19

We have been working on a big update of our website for a while, and it is finally ready to see the light of day!

The primary change is a new URL structure to allow us to keep permanent URLs for everything going forward. This does mean we've had to change the URLs for the BornHack 2016 content, sorry about that.

All the old BornHack 2016 content is available at and BornHack 2017 stuff is starting to show up at /bornhack-2017/.

If you spot any issues with the website please let us know - ideally by opening a Github issue, but a heads up on IRC is fine too.

We finally have t-shirts and hoodies available the shop again. The t-shirts are identical to the ones you could buy just before the event. The hoodies are identical to the ones worn by the organisers (except without the text "Organizer" on the back).

The prices of this new batch of merchandise include shipping (domestic or foreign). A whole bunch of legal stuff prevents us from accepting credit card payments for items being shipped, so please pay with bank transfer, bitcoin, or in cash to an organiser (if you happen to find yourself near one).

Note: This batch of merchandise will only be for sale the rest of November so get your orders in before December begins. Orders will be produced and shipped out during December.

Remember to put your shipping address in the comments field in the order!

Badge Contest Winner Found 2016-09-23

We found a winner of the BornHack 2016 badge hacking contest! Even though we only had one entry we still think it is an awesome badge well worthy of winning the price.

The only way to participate was by submitting a pull request to the Github badge contest page. This means that you can now go see pictures and all the components used to make the winning badge there.

Congratulations to the winner! He won tickets to Copenhagen Maker this weekend, an exciting new maker festival.

BornHack takes place on a uniquely beautiful island. It would be a shame to spend a week there and only see the BornHack venue!

We have ten bicycles (including lights, a lock and a helmet) available that are free to borrow for BornHack participants. The bicycles are equipped with large baskets, so they can be used for both sightseeing and shopping.

They can be booked free of charge at the infodesk.

Ticket Contest 2016-08-15

We are hereby announcing a ticket contest in which we are giving away three (3) standard tickets (normal price: 1200,- per ticket) for BornHack 2016.

To take part in the contest all you have to do is send us an email describing your interests/projects, and why you want to go to BornHack. The lucky winners will be notified directly on friday the 19th of august.

Please send your replies to to take part in the contest!

Announcing the BornHack 2016 Badge 2016-08-14

We are excited to announce that all participants at BornHack 2016 will receive an electronic name badge. From the get-go the badge is a Joule Thief circuit powering an LED to light up the name of the owner.

You can see a picture of the kit here and an assembled badge here. We also caught a picture of an assembled badge by night, and we have a rendering of the lanyards that come with the name badges.

The badge is designed with a large prototyping area (both hole-through and surface-mount) which you can use to modify the badge. At the end of the week the three best badge hacks will win prices and fame. Read more about the badge at our info page and on Github.

We owe a big thank you to Thomas Flummer from Danish makerspace Labitat for helping out with the design and production of the badges. You can meet Thomas at the Badge Workshop monday evening.

We also want to thank the sponsor of the badges, TykTech.

Rent a Fridge Shelf 2016-08-13

To help participants keep groceries chilled until they are needed we have fridges available. You can rent a shelf for 100,- for the entire week, or a smaller drawer for 50,- for the week. The fridges look like this and can be ordered in the shop. Note: Does not come with bowls of toast bread or glasses of juice like in the picture.

You are also welcome to bring your own fridges or coolers!

Talk: How present day banking malware works? From Spam emails to money transfer 2016-08-12

Present day malware is very sophisticated and much different than a decade ago. Malware is no longer a single executable file which executes on the victim's computer and runs as a process. There are multiple stages involved from a typical malware infection to completion of its objectives. Typically, infection starts with a victim clicking on a link in a spam email. It then leads to a binary executable downloaded and executed on the victim's computer. This is however, just the tip of the iceberg, the executed binary usually downloads further binaries from internet and creates several processes, registry keys and injects into legitimate process’s memory. After a series of steps, the money is transferred from victim's bank account to a bank account controlled by criminals.

This talk will explain the events from spam email to money transfer step by step to help the audience understand malware and protect themselves better.

The Practice Lock Exchange 2016-08-12

Many hackers enjoy lock picking on a hobby level, to the extent where hacker festivals often have villages dedicated to lockpicking. At the moment it doesn't look like BornHack will have a dedicated lockpick village, but we do have another initiative which can be beneficial to lock pickers.

Lock pickers often have a bunch of practice locks. Often a hacker will have picked those same practice locks many, many times. The BornHack shop will have a "practice lock exchange" where you can hand in one of your practice locks that you are tired of, and take another from the pile.

We will "bootstrap" the practice lock exchange with a few locks to get things going. Hackers should bring all the locks they have, along with their lockpicking tools of course.

Happy picking!

Village table and chair prices lowered 2016-08-11

When we lowered the prices of village tents a week ago we forgot to update the prices of tables and chairs. The shop now has chairs for 20,- or 25,- DKK instead of 75,- DKK, and tables for 60,- DKK instead of 215,- DKK. This is about the same level of price reduction we saw with the tents.

Happy village shopping!

Talk: American Fuzzy Lop and Address Sanitizer 2016-08-11

We have powerful and easy to use tools that can vastly improve the quality and security of the code we use everyday.

Code written in C and C++ is often riddled with bugs in the memory management. Out of bounds accesses, use after free errors and other issues can hamper the security and stability of applications. Unfortunately many free software developers don't use freely available tools that easily allow finding and eliminating many of these bugs. The talk will encourage developers to change that and integrate these tools into their development process.

Hanno Böck

Hanno Böck started the Fuzzing Project in 2014 as an effort to improve the security of free software code. In May the Linux Foundation's Core Infrastructure Initiative decided to fund this work. He is also working as a freelance journalist and regularly writes about IT security issues for various publications. He is the author of the monthly Bulletproof TLS Newsletter.

Talk: Running "server-less" applications in the cloud using AWS Lambda 2016-08-11

When moving workloads to the "cloud", why settle for simply running virtual machines, that might as well be running in the datacenter. Why spend time maintaining the operating system layer at all? Using AWS Lambda it is now possible to run code without caring about the underlying operating system. AWS Lambda will scale the code to run on as many machines is necessary to answer the requests. But how does it work? What tools can be used to use it effeciently? How can we build a simple web service using a bit of Python code, and some AWS magic.

Loke Dupont

Loke Dupont is currently Head of Services with Xstream and has worked with streaming video technology since 2008 for Xstream and TDC. He has worked with plenty of different video encoders, streaming servers and DRM technology.

Lately he has been focused on AWS, and how to move web applications to the "cloud" as well as building AWS native applications.

Talk: European politics: What you can do for me^H^H all of us. 2016-08-10

There is an abundance of proposed laws, regulations, initatiatives, trade agreements, etc., that we all can see will do nothing good for our security and privacy. A lot of the technology most people use every day seems to be designed to undermine our right to privacy.

Some of this is caused by a fundamental lack of understanding of technology, some on greed, some is just evil.

We can fight this on a political level, as e.g., European Digital Rights and IT-Pol do.

But we can also oppose it from our home ground. Using techology. We already have, of course. Imagine where we would be without Free Software, PGP, TOR, Blockchains, etc.

But where do we stand today? And how do we take advantage of our hacker skills. I will give a brief overviews based mostly on current European politics. Then we will have an open discussion about the way forward.

Niels Elgaard Larsen

Niels have been teaching Computer Science at University of Copenhagen, later worked on optimization, databases, and administrative system. He now do IT consulting and training courses based on Free Software.

Niels is vice-chairman of IT-Political Association of Denmark and has been fighting for digital rights in Denmark and Europe for two decades.

Unable to afford a ticket? 2016-08-09

If you want to go to BornHack, but you are unable to go because you can't afford a ticket, please contact us. We will work something out.

We would hate to see anyone miss this event because they can't afford a ticket. BornHack is about hackers getting together to share knowledge, grow friendships, and build things. We want to do ours to make sure money doesn't get in the way of that.

Please get in touch! Write to

Schedule Published 2016-08-09

We have been working hard on our schedule system and it is finally finished. Not all talks, keynotes and workshops have been scheduled yet though, so stay tuned.

You can see a list of all speakers and a list of all talks, keynotes and workshops, or go straight to the schedule.

Venue Map Published 2016-08-09

After much drone flying and graphics work the map of the BornHack venue is finally ready for public viewing. The map can be found in the map part of the info section.

The rest of the info section has been updated with much new information about all things BornHack. Be sure to read through it so you don't miss anything important!

Talk: Designing Composable Security 2016-08-08

"Lots of things are wrong with the internet, everything sucks" is a recurring theme at many tech events like this. But there is not enough focus on concrete long-term fixes. Discussions of security topics are not systematic enough, and people and companies pushing selfish agendas makes these problems worse.

In this talk we suggest better "ground-up" approaches to secure system design. Composability is the key idea here; we'll discuss both abstract principles for achieving this, as well as concrete components that "someone should make" that would compose with other future components. Thus, different teams can work together towards a common goal instead of competing for each others' users and volunteers. Any backwards-compatibility hacks may be decomposed away when no longer needed, instead of permanently polluting other parts of the ecosystem.

Workshop: v2 2016-08-07


Talk: Introduction to Modern Video Streaming Technology 2016-08-07

How can you stream to users on a wealth of devices using a few simple formats? How can you make sure that all users can watch your video with changing network conditions and over unstable network links? We will go through some fo the technology behind video streaming technology as used by almost all larger video streaming services today. We will also walk through how to use open source tools to achieve comparable quality to the big guys, and how to setup players across a bunch of platforms. Tools used will be ffmpeg, Bento4, Shaka Player etc.

Loke Dupont

Loke Dupont is currently Head of Services with Xstream and has worked with streaming video technology since 2008 for Xstream and TDC. He has worked with plenty of different video encoders, streaming servers and DRM technology.

Shuttle Bus Service 2016-08-05

We are happy to announce that BornHack will have a shuttle bus to help participants get around.

The shuttle bus seats 8 passengers and a driver, and has room for groceries.

On the arrival day you will be able to call the BornHack phone number (which will be published later) to arrange pickup. During the festival and on the departure day you will use a reservation system to let us know when you need transportation. We wont have time for something fancy, so the reservation system might just be a whiteboard at the infodesk where you write yourself in :)

If you want to help BornHack by taking a shift or two driving the shuttle bus please let us know as soon as possible! We need the drivers license info for the car rental place.

Village tent prices considerably reduced 2016-08-04

We are very pleased to announce that we closed a deal with a new village tent supplier today, resulting in considerably lower prices. The savings range from 25% on the smaller and up to 60% on the biggest tents! Note that BornHack does not make a profit on village tents - neither with the old nor with the new supplier. The prices have already been updated in the shop.

We put a lot of effort into picking the right suppliers for the different parts of BornHack. Since Bornholm is an island we prefer local suppliers whenever possible. Saving transportation costs (both financial and environmental) is a big factor when choosing suppliers. But in this case the difference in price between the local and a mainland vendor was simply too big to ignore.

We understand that these new prices will allow more camps and villages to rent a tent for BornHack and we are obviously thrilled about that.

Please note that village tents must be ordered no later than August 21st!

Talk: Technical and Political Aspects of Running Uncensored DNS servers 2016-08-04

The UncensoredDNS project was started almost 7 years ago, back in November 2009. People were asking for recommendations for alternatives to their ISP's censored DNS servers.

Back then OpenDNS did NXDOMAIN redirection, an advertising trick where misspelled nonexistant domains are redirected to a search page with ads instead of returning an NXDOMAIN error. They also didn't have ipv6 or DNSSEC, both of which are mandatory on a modern DNS server, even back in 2009.

Even if Google DNS had existed back then I wouldn't have felt comfortable recommending them either. While they do run a stable, fast and largely uncensored service, I am not convinced that it is a good idea to hand over all your DNS lookups to Google.

All this prompted me to do something about the situation so I started UncensoredDNS with help from friends. I also give talks to explain why I am doing this, since people naturally have an easier time trusting a service if they know who is behind it.

The talk be a state-of-the-dns type thing, with some political but mostly technical content. The technical content will include statistics, background and status on the anycast project, dnscrypt, the openvpn project, the move to ansible, the new dns-over-http proposal, and more.

Talk: GraphQL - A Data Language 2016-07-20

GraphQL is a query-language for data, intended for the modern internet clients on the web and inside mobile phones, invented inside Facebook around 2012, it is currently in a draft specification phase with several open source implementations of the underlying ideas.

The main feature of GraphQL is a shift away from RESTful services where all of the query declaration is on the server side, to one where the client is in control of declaring what it wants. The result is a system which is easy to work with for the front-end developer. GraphQL also supports backward compatibility to earlier client versions. All while being able to maintain a security level at least as good as REST. On the server side, GraphQL provides much the same benefits, acting as a protocol and contract between the server and client.

This talk presents GraphQL itself, and also presents how one goes about building an implementation of the language. The running example is a GraphQL compiler written for Erlang.

Jesper Louis Andersen

Jesper Louis Andersen bridges the gap between theory and practice. He has a curiosity for programming language theory, math, and logic, but dabbles in many other fields of computer science as well.

Cheap transport from Copenhagen to BornHack 2016-07-16

PROSA, the union of IT-professionals in Denmark has set up a great deal for BornHack attendees traveling from Copenhagen to BornHack. For only 125kr, about 17 euros, you can be transported to the camp, and back to Copenhagen at the end of the camp!

We encourage our attendees to make use of this offer!

The bus has the following schedule:

PROSA might contact you with details regarding the bus, but nothing more!

Talk: OE-lite - Hack on Your Own Devices 2016-07-15

Have you ever wanted to do something cool with one of your electronic devices, but been stopped from doing it because the vendor did not think of that use-case? Have you ever found a problem with the code on one of your devices but being unable to fix it because the vendor no longer cared about the software or did not allow modifications?

Have you ever had to throw out perfectly good hardware since the software was no longer updated/working?

I have :) And it makes me annoyed every time!

Instead of being in the hands of the vendor of your NAS, router, media-center etc. how about actually controlling it yourself?

In this talk I will present a framework (OE-lite) to build custom embedded Linux from scratch. I will talk about why it is simply not good enough to “just install Ubuntu on the damn thing!” and walk through my own use-case of building a router from a BananaPI-R1 board.

OE-lite is a mature framework for creating robust, maintainable custom Linux platforms. Originally forked from OpenEmbedded to showcase how to improve on major technical defects, today OE-lite is a serious alternative to frameworks like Yocto, buildroot or OpenWRT. With a strong focus on avoiding surprises when developing custom Linux systems, working with very different hardware platforms from the same codebase and maintaining the systems for 10 - 15 years OE-lite offers another perspective on embedded Linux systems. The project have not been very public, but we have been working hard to change that and we are now inviting embedded Linux developers to come join us!

Kim has a background in academia doing a PhD in wireless communication performance optimizations.

Keynote: Security for non-hackers beyond »Use Tor. Use Signal.« 2016-07-13

Individual and organizational security needs are seldom simply a technical challenge but rather an operational one. »How do we get things done with minimal interference from those who would rather not see us getting it done?« That is the question facing journalists, activists and human rights defenders of all stripes around the world.

In order to provide a practical answer we need to go further than tool guides and how-tos. We need to establish baselines of digital literacy and security thinking, and build up the collective habits commonly known as 'security culture'.

This talk lays some conceptual groundwork for integrating security into the modes of operation of newsrooms, the offices of NGOs and law firms, activist affinity groups and other forms of organization with unmet security needs. It is directed for non-hackers and hackers alike.

Henrik Chulu

Henrik Chulu is a co-founder of the Danish internet policy think tank Bitbureauet. He likes to think and write about digital security and other forms of information asymmetry.

Talk: TLS attacks and the burden of faulty TLS implementations 2016-07-11

TLS is by far the most important cryptographic protocol in use today. In recent years TLS received much more attention from security researchers. Implementation errors like Heartbleed and protocol bugs like BEAST, Lucky Thirteen, DROWN and many more have made headlines.

Faulty implementations can enable attacks. In some cases they can even be a security risk for uninvolved third parties and endanger the whole TLS ecosystem. Especially so-called Enterprise devices that have their own TLS stack are often a reason for concern.

The speaker will give an overview of implementation errors that happened in various TLS stacks and will shed light on this underappreciated problem.

Hanno Böck

Hanno Böck started the Fuzzing Project in 2014 as an effort to improve the security of free software code. In May the Linux Foundation's Core Infrastructure Initiative decided to fund this work.

Village registration now open 2016-07-11

Everything is better with a proper homebase!

Camps on BornHack can register as villages. A village can have a common theme like a project, people from the same country or city, a hackerspace, a programming language, and so on - or it can just be a bunch of friends camping together.

If you feel like opening your village up to others you can add a nice description to reach out to likeminded and interested people. It is also perfectly fine to keep your village "invite only" if you want to. Just check the "private" checkbox when registering the village to do so.

Register your village now, or join an existing village. You can also rent a big tent for your village, or you can bring your own.

We encourage all camps and villages to bring all the lights! Decorate your home base with as much pretty lighting as possible. It makes for a beautiful sight at nighttime when walking around.

We also very much welcome you to do any kind of installations on the campground, and to run events or projects that do not fit the workshop/talk format. Contact us if you want to do anything outside of your village area, or if you want your activities announced. If you have any other questions, don't hesitate to contact us.

Cabin price halving 2016-07-10

To celebrate the Bitcoin block reward halving we're doing our own BornHack cabin price halving!

You can now rent a bed in one of our three cabins for 150 DKK for a single night, and 1000 DKK for the whole camp.

It is also possible to rent a whole cabin if you are a group of up to 8 people, this now costs 7500 DKK

See and rent the cabins on:

Talk: MirageOS - robust operating system design from the grounds up 2016-07-08

Contemporary operating systems suffer from being enormous code bases, riddled with bugs, still supporting legacy hardware (like floppy drives). A common attack vector is based on unsafe memory operations - lack of bounds checks (buffer overflows) and temporal memory safety violations (double free, use after free).

But the environment changed: for security reasons, each service is usually isolated in its own virtual machine, and the virtual machines are scheduled by the hypervisor onto the physical hardware. The requirements for operating systems changed, but most operating systems are only extended to support more complex environments.

In this talk I will present a radical approach to operating systems design: back to ring 0, starting from scratch. Programming language technology has progressed since UNIX was written in C, automated memory management is widely used, strong and static types are usable, and we learned how to build reusable libraries and package those.

MirageOS is a library operating system written mostly in OCaml, a functional and modular programming language. It targets hypervisors, thus does not contain hardware-specific drivers, but generic drivers (e.g. a VirtIO network driver). Each MirageOS application consists of only those OCaml libraries required - why should my name server have user management and a file system? The lines of code, and thus the attack vectors, are drastically reduced. We already implemented various common network protocols, such as HTTP, TCP/IP, TLS, DHCP.

I will explain the design and implementation of our TLS stack in more detail, which separates the effectful bits from the protocol logic very clearly, while preserving reasonable performance.


Hannes Mehnert

Hannes Mehnert is currently a PostDoc at the University of Cambridge. In his spare time, he is not only a hacker, coauthor of a book on indian cuisine and functional programming in JavaScript, but also a barista and likes to travel with and repair his recumbent bicycle.

He researches in several engineering areas: from programming languages (such as compiler optimisation visualisation and type systems) over full functional correctness proofs of object-oriented code, development environments for dependently typed languages, to re-engineering network protocols (TCP/IP) and security protocols (TLS, OTR). He feels safe in a garbage collected environment, and appreciates the expressive power of declarative purely functional code.


Keynote: Words and Power - are we making the most of online activism? 2016-07-06

For years, big names like Ed Snowden and Chelsea Manning have given up their lives in order to protect regular people like you and me from breaches of our privacy. But we are still struggling with getting people interested in internet privacy. Why is this, and what can we do? Using experience from communicating privacy issues on multiple levels for a couple of years, I have encountered some deep seated issues in the way we talk about what privacy means. Are we good enough at letting people know what's going on?

Emma Holten

Emma Holten is a feminist and human rights activist. She is co-founder and editor of the standard critical magazine Friktion and also a student at the University of Copenhagen. She speaks in both national and global contexts of feminism, digital activism and why privacy on the internet is crucial to a democracy, where everyone is equal.

Talk: Checking a Distributed Hash Table for Correctness 2016-07-04

Distributed Hash Tables are used as name-lookups in large decentralized distributed systems such as peer-to-peer networks and loosely connected machine clusters. Correctness is complicated by their distributed nature. This talk presents an implementation of one such DHT, written in Erlang, based on the Kademlia data structure. Its unique feature is that it comes equipped with a full QuickCheck specification, which semi-formally verifies its correct behaviour through random test generation.

The talk focuses on the test aspect of the system, and how one builds fairly large QuickCheck specifications for real-world systems, in particular by slicing a large specification into isolated parts and then reassembling those parts into a full model. It is intended to give people an overview of how to attack larger code bases with (semi-) formal methods.

Talk: Privacy, Data Protection, Security and Law: Practical Steps Forward (a Swedish Perspective) 2016-06-29

A new data protection regulation, increasing pressure on legislatures to circumvent or side-step human rights and a faltering technical infrastructure that isn't up to the task of protecting the individual are some of the challenges for humanity at this ever crucial point in time. is a Swedish NGO which has been working since spring 2015 raising these issues in the Swedish executive. Through advocacy work, we raise important individual and consumer security concerns, but we have also developed a simple web-tool which allows web masters - or their visitors - to request simple, cheap and fast implementation of technical measures to improve data protection qualities of a website. We will present our work in spring 2016 developing the tool, the criteria with which we measure a data protecting web, and some of our additional advocacy work in the field of data protection in Sweden.


Amelia Andersdotter and Anders Jensen-Urstad have worked in the European Parliament for several years. Since 2014 they run, and since spring 2015 is a Swedish NGO. Anders brings technical expertise to the core of the organisation, while Amelia is the policy-ninja.

Talk: Code is Politics 2016-06-27

“Code is law” wrote Lawrence Lessig back in 1999. This has evolved and been demonstrated again and again since then. Code defines an ever increasing part of our personal and social lives. How businesses and friends interact with us, but also how authorities and intelligence services see us. It is already the case for many but soon the lives and rights as citizens of all of us will be defined by code. Code is political. Politics depend on code. If we want a world that is open and diverse we must code for it. How do we achieve better code, better politics and a better world together?

Karen Melchior

Karen Melchior is a Danish diplomat turned politician and digital activist. After six years in the diplomatic service she decided to get involved in politics when she returned to Copenhagen in 2012. The Danish cartoon crisis in 2006 and the “Arab spring” 2011 sparked her interest in digital diplomacy and the power of online networks. The fight for an open and free internet has been at the centre of her political work as she sees this as the only way to ensure freedom of speech and democracy around the world. The Snowden revelations underlined for her how our civil rights are being undermined even by our own governments. Part of Karen’s political work looks to improve our political culture in a time where “filter bubbles” and polarisation seem more common than real dialogue. Karen stood for election for the European Parliament in 2014 and for the Danish Folketing in 2015. She was not elected and still works for the Danish Foreign Service.

Talk: How to (not) Store Your Password 2016-06-24

There is much dispute on how to securely store passwords. Traditionally there are two schools: Online and Offline password management. Both have strengths and weaknesses when it comes to security as well as accessibility and portability. Both methods have one weakness in common though: they store your password. In this talk I will discuss the various strengths and weaknesses of traditional password managers and present a method that has the main strengths of both online and offline password managers, but allows you to generate secure passwords on-the-fly, never to store them again.

Ronni Elken Lindsgaard

Ronni Elken Lindsgaard is maintainer and primary developer of RndPhrase. He works as Software Engineer for a Danish security company and is active in various open source projects and local groups in Copenhagen related to personal security and privacy awareness.

Keynote: Infocalypse Now - and how to Survive It? 2016-06-22

Digitalization is on everybodys mind - and so is control and registration of citizens. States and businesses all choose sadly unsecure data-silo-systems and piles up sensitive data without securing anything. Critical Infrastructure is privatized and sold off and secure, analog systems are being torn down in the name of progress. Its an evolving Infocalypse, where all info can be manipulated, stolen and used, our money system, personal data and administrations are doomed in a world of greedy blackhats, cyberwarfare-troops, autonomous drones, herfbombs, solarstorms and intelligence agencies on steroids The Beast is unleashed, can it be stopped, or is it anyone for him self?

Anders Kjærulff

Anders Kjærulff is a jounalist, poet, technology-critic and radiohost with a weekly, one hour radioshow on privacy and data protection. He is currently working on a dystopic book about the end of all privacy and the dim future, that lies ahead.


Workshop: Django Crash Course and hands-on Workshop 2016-06-20

Duration: 3 hours
Seats: 20
Need to know: Programming experience (preferably Python [0]),
Nice to know: HTTP knowledge [1], Git [2]

Django [3] is "the web framework for perfectionists with deadlines". The framework has existed for over 10 years and is thus full of highly refined design principles, yet it continues to innovate and streamline its practices. The developer scene of Django is continuing to grow, and people use for anything from prototyping to production sites with millions on users. Django is written in the Python programming language.

As open source developers and community people, we think Django is the most awesome framework for building web applications and you should learn it. Bring your laptop and we'll install and introduce Django and its concept. After that, we'll create a Django project together and dive into it head-first.

First half

During the first part of the workshop, we'll install Django and a virtual python environment.

Then we'll introduce Django's layers and components such as the request-response loop, how URLs are handled, static files etc.

Second half

Once we're done with the basics, we'll try to introduce some hands-on higher level work and let you hack on your own project.

If you don't have your own project, don't worry! We'll bring our favourite ecological food coop project Eggplant [4], which we regard as not just another open source project, but a best practice arena for the Danish Django community. We'll have beginner-friendly issues ready on Github, and if you do a PR, we'll make sure to review it in the strictest manner possible!


Benjamin Bach and Víðir Valberg Guðmundsson have both been developing Django for 8+ years, working professionally with Django websites on a daily basis and putting efforts into reusable open source django applications. Both are active in the Copenhagen Django Meetup Group, and invite you to join them on IRC at #djangocph @



Talk: Bluetooth Low Energy 2016-06-17

BLE provides versatile wireless communication at a very low power consumption, especially compared to classic Bluetooth and WiFi.

It has a wide range of uses where proximity detection is used for a lot of applications such as alerting when a keychain goes out of range or requesting alerts from lost objects. Among consumer products, Apple iBeacons is a notable application of the technology. However, it is also used for human input devices such as mice and keyboards as well as various forms of sensors, e.g. temperature, heart rate, etc.

BLE enables devices to run off coincell batteries for years while retaining connections or doing periodic broadcasting. This makes the technology appealing for the maker community for applications that are power-constrained, e.g. due to having a limited power-budget (say, running off a small PV-cell) or running off a battery.

This talk explains how the low power consumption is achieved, what the possible topologies are, and how this affects the types of applications you can build on top. Finally, a low-level demonstration of interfacing with a BLE controller is performed.

Talk: Running Exit Nodes in the North 2016-06-15

Tor is free software and an open network that helps you defend against traffic analysis, a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security.

People can donate their bandwidth to the Tor network and support human rights. Many people in Finland have done this.

Especially Tor network needs fast exit nodes which are final nodes before traffic reaches its destination. Because Tor traffic exits through these relays, the IP address of the exit relay is interpreted as the source of the traffic.

If a malicious user employs the Tor network to do something that might be objectionable or illegal, the exit relay may take the blame. People who run exit relays should be prepared to deal with complaints, copyright takedown notices, and the possibility that their servers may attract the attention of law enforcement agencies.

In Finland, Juha Nurmi has been establishing good relationships with ISPs and law enforcement agencies to keep Finnish exit nodes online.

Juha Nurmi (age 28) is the founder and project leader of the Ahmia search engine project. He is a security researcher and has been involved in numerous projects funded by both the commercial and government spheres, including DARPA Memex project in the Silicon Valley. Juha is also a noted lecturer and public speaker. Juha's work on Ahmia has been in part sponsored by the Google Summer of Code.

Credit card payments enabled 2016-06-14

A unexpected anonymous benefactor stepped forward and put up security we can accept credit card payments after all. We are very grateful for this since many of our guests prefer credit cards.

If at all possible we still encourage people to use bank transfers or blockchain payments though, since they are easier and considerably less expensive for us to handle on the backend.

But credit card payments are open and working now, so if you've been waiting for them, go buy your tickets!

Talk: Simulated DDoS Attacks, Breaking the Firewall Infrastructure 2016-06-13

DDoS Attacks have become a daily annoyance for many, and we need to create robust infrastructure. This tutorial will go through a proposed method for testing your own infrastructure using off-the-shelf tools like packet generators hping3 and t50 on Kali Linux.

The goal for the tutorial is to explain:

The content will include:

There won’t be any exercises, but I recommend trying to install Kali Linux on a Virtual Machine to get familiar with this Linux distribution.

I will be doing demos showing how I run commands and monitor a DDoS simulation.

Talk: Keyless Entry Exploration and Exploitation 2016-06-10

This presentation will provide a walkthrough of the audit process of an IP-enabled physical access control device.

Knud aims to cover some information about the methodology used during the process, but will mostly be discussing the (interesting or sad, depending on the view) results of said audit. The presentation builds on work done on and off over a few iterations of the product.

Talk: Incompleteness Phenomena in Mathematics: From Kurt Gödel to Harvey Friedman 2016-06-09

In the first half of the 20th century the dreams of a complete and consistent formalization of mathematics was destroyed, when Kurt Gödel proved the existence of true but unprovable sentences in every reasonable formalization of mathematics.

However, the explicit sentence constructed in the proof was tailored to cause trouble and therefore was not of much interest to mathematicians in general. Since then various incompleteness phenomena have been discovered and many of these (relative) unprovable sentences are of genuine mathematical interest. In recent years Harvey Friedman have taken this enterprise to a new level by constructing sentences about "low level" mathematics and showed that these sentences are provably equivalent to the consistency of axiomatic systems far stronger than classical set theory (ZFC). In this talk I will try to introduce concepts of mathematical logic together with some highlights in the history of incompleteness phenomena and discuss the philosophical implications of these.

Note that these (early 20th century) developments also play an important role in developing the theoretical computer.

No credit card payments after all 2016-06-08

Unfortunately we will not be able to accept credit card payments in the webshop as expected.

The traditional payment providers make accepting credit cards difficult for new events like ours. We tried different approaches but we have been unable to make it work.

We encourage everyone to use blockchain payment or bank transfers instead. We realize that this is an inconvenience for some, but we hope that this will not discourage you from attending. The ticket shop is open, go get your tickets! :)

On behalf of the BornHack organizers,


Payment options 2016-06-02

At the moment the shop has two payment options:

A bank transfer doesn't need much explanation except to say that they can be rather slow, especially if you are outside the SEPA region. You need to allow for up to a week before we register your transfer and mark your order as paid. Not the fastest, but widely supported.

You also have the option of using one of a bunch of different blockchain payments methods. Supported currencies include Bitcoin of course, but also Ether, Litecoin, Dogecoin and a bunch of other options. You can see the full list here. Apart from being cool, paying your ticket in cryptocurrency is also fast - you will be able to download your ticket in minutes, if not seconds.

Finally we will also be accepting credit cards from Visa, Mastercard and the Danish Dankort soon. We still need to check a couple of boxes before it can happen, but it should be available in days, not weeks.

The ticket shop is now officially open 2016-06-01

TL;DR: Tickets are out, if you buy a cabin spot please remember to buy an ordinary ticket as well. Call for speakers will be out shortly. A call for sponsors will also be available shortly. Thank you.

We are very happy to officially open the BornHack shop for ticket sales. It is possible to buy a variety of tickets. Hopefully this post will make it easier for you to decide what ticket is right for you.

It is also possible to buy a ticket for a bus transportation sponsored by PROSA. This ticket will only be available for PROSA members for the first 14 days - after that it will be available for non-members as well for the same price. More information about the transport will be available at a later point in time.

T-shirts and other merchandise will be available for sale later.

Speaking at BornHack

A call for speakers will be announced soon. Please start preparing your titles, abstracts and biographies for us.

The model we are going to run with is that we hope that most of the speakers will participate in BornHack for the entire week and will buy their own ticket. If you cannot stay for the entire week we will provide you with a one day ticket to the event and you will have to pay for transportation to and from the island yourself. For keynotes we pay transport and tickets - we reach out to keynotes ourselves, but if you have a presentation that you believe would be keynote material you are very welcome to reach out to us yourself once the call for speakers is announced.

Sponsoring BornHack

A call for sponsors will be announced very soon.
